Returns the index values of the rows that get a window and one group per such row. options.placement is only supported without group_by.

Source

fn group_by_dynamic( &self, group_by: Option<Vec<[u32; 2]>>, options: &DynamicGroupOptionsIR, ) -> Result<(Column, Vec<Column>, GroupPositions), PolarsError>

Returns: time_keys, keys, groupsproxy.
